I have installed cento 5.3. I enabled the ssh deamon. I have found that 2 options that I normally use does respond as I expect. Has anyone else had similar problems with the following options in sshd_config:

• Port 6666 – if I set the port to anything other than 22 (default),

using ssh –p6666 name@servername, does not work. Yet if I leave keep the default, then ssh name@servername allows me to login.

Did you check your iptables rules ? port 6666 is closed by default. I use a sshd with port 443, so it should work.

• PasswordAuthentication no – if I set this option to “no” (default is

“yes”), and my ssh key is either missing or in error, I will be prompted for user system login password. If this is set to “no”, it should not allow me to login if I have not ssh key specified or in error. Has anyone else run into this problem.

Erhm.. I remember it does ask for a password but just doesn't let you in. But I can me mistaken :)

This is related to PAM authentication, which is what is used in (most) Linux systems. To prevent sshd from authenticating with passwords I believe you have to set "ChallengeResponseAuthentication no" instead, at least that is what I gather from reading the comments in /etc/ssh/sshd_config.
